How to create text input button based on the data set?

[Ethan Ji]

Hi I have the shiny R codes like below:

library(shiny)

ui <- fluidPage(

 
  inputPanel(
    textInput ("target_1", "enter target 1")
  )
 
 
)

server <- function(input, output) {
 
  my_df <- data.frame(a=letters[1:4],b=LETTERS[1:4])

 
}

shinyApp(ui = ui, server = server)

If I have 2 columns in the data set, I want to create 2 text input buttons, if I have 3 columns in the data set, I want to create 3 text input buttons. How can I automatically create the text input buttons based on how many columns the data set has? Can anyone help me? Thanks!
